Component: ffmpegundetermined
Resolution: invalid
Status: newclosed

This does not look like an issue that can be fixed in the FFmpeg source code.
(Update your libx265?)

comment:2 by Balling, 3 years ago

No need to update.

This is a WONTFIX bug in ffmpeg.

See "except those CLI-only ones, those are only used with x265 binary directly"

Did you use to extract RPU?

Then you can use this command to encode.

Other affected commands: zonefile qpfile dolby-vision-rpu recon

I am going to reopen this since I am sure you can hack CLI-only option somehow and we are planning to somehow pass RPU metadata to x265, see 54e65aa38abb37d6af92551b7e3adf6785f631ec (Dolby Vision RPU data, suitable for passing to x265 or other libraries).

Nice test file also:

Any updates here? I also would love to have support for the dolby-vision-rpu='dolby_vision.bin' parameter directly. At least x265 supports it, but not ffmpeg using -x265-params
